Just ask 5-year-old Pierce Griffin, of Augusta, Georgia, who could be seen in a viral video giving his dead fish a tearful send off as he and his mom flushed it down the toilet.

His mom, Dee Griffin, told InsideEdition.com that the fish, who Pierce named Cupid, was a Christmas present from Santa Claus.

But, on unlucky Friday the 13th, Pierce accidentally gave Cupid too much food.

"The next day, he walked past the bowl and he didn't say anything," Griffin said. "I look and it's dead."

Although she originally considered swapping out the beloved pet before her son noticed, she eventually decided to break the bad news.

"I said, 'I have to tell you something,'" she said, "and he starts crying."

The boy then ran to the bathroom and locked the door when his mom suggested they flush it. He could even be seen in the video posted to Facebook blocking the path to the toilet, sobbing. "Unless we get another one, I don't want to."
